3 Claims. (Cl. 98-94) This invention relates to air conditioning apparatus.

An object of the invention is to provide improved means for conditioning air and more particularly to iilter air by which foreign particles.

. which air is passed for iiltering. The invention contemplates the circulation of room air, or air taken from the outside, or a mixture of both. Air is circulated through the chamber by means of a power operated fan -which may be positioned within the chamber.

An illustrative embodiment of the invention is shown in the accompanying drawing, in which: Fig. 1 is a side elevational view. partly in section, of an apparatus embodying the invention.

Fig. 2 is an end elevational view taken in the direction of the arrows 2-2 of Fig. l.

Figs. 3 and'4 are transverse sections taken on the lines 3-3' and 4 4, respectively, of Fig. 1.

Referring to the drawing, there is shown an air chamber comprising sections 6 and 8 mounted on a base I0 having an end resting upon and supported by a sill in the window opening of a room wall I2. The opposite end of the base I0' rests upon legs Il located' inwardly of the room wall I2. The section 6 is slidably mounted may also lbe drawn into the section 8 through on the base I0 for longitudinal movement relative to the section 8. The base Ill has a longitudinally extending slot Il receiving a bolt I5 carried in the bottom'wall of the section 8. The base Ill forms the bottom wall of the section 8.

Outside air is drawn into the section 8 through the open end of the latter and a laterally slidable door I6 controls the opening and the amount of air entering the chamber therethrough. Room air of the shutter controlled openings I1 in the side and top walls of the section 8 is a illter 2| through which air from the outside and also from the room is passed for the purpose of removing harmful irritants, such as pollen. While the air 5 chamber is shown as comprising two sections, it will be understood that such chamber may comprise a single chamber if desired.

Air is drawn into the chamber 'and discharged therefrom by means of a fan 26 mounted on the bottom wall of the section 8. A wall 28 havingv a central opening 30 is positioned inwardly of the fan'26, as shown in Fig. 1. The discharge end of the section is provided with a iilter 32, similar to the filter 24. These lters preferably comprise a compact mass of spun glass fibers treated with a collective agent such as a nondrying oil or other substance that will collect fine particles-of dust pollen and the like ordinarily invisible to the naked. eye. The iilters are 2o preferably made in the form of pads which may be readily replaced. It will be understood, of course,A that the invention in its broader aspects is riot limited to the particular formation of the :filtering elements set forth. 25

The apparatus is particularly advantageous in affording relief to those suiierlng from hay fever and similar ailments. It is adapted to be installed in a room and may be so conditioned that room air only is passed through the apparatus for condltioning. or if desired air may be taken from the outside only, or a mixture 'of room and outside air passed into and filtered simultaneously. When it is desired to quickly condition room air, the sec-v tion 8 is moved to the position indicated in Fig. 1 and the slide door 22 moved to close the innermost opening in the section 8. With the apparatus in this position there is a circulation and iiltering of room air only, the conditioning of the air being eii'ected in a relatively short time as the air course is shortened and there is but a single ltering. Further and increased circulav tion of room air results from moving the section i 6 against the section 8, thereby forming a single chamber, and by adjusting the door 22 and shutters I8 room air is drawn into the chamber and passes through both iilters 24 and 32. This results in a more thorough nltering.

When the parts are in the position just ldescribed the air supply can be taken from the outside through the opening in the wall I2 by merely adjusting the slide door I6, air so taken mingling with the room air drawn into the chamber through the openings I1 in the walls of the section 8. If desired, a supply of fresh air 'only may be admitted from the outside by closing the shutters I8. It will thus be seen that provision is made for the conditioning of room air only, or both room and outside air, or outside air only.

Various changes including the size, shape and arrangement of parts may be made without departing from the spirit of the invention, and it is not our intention to limit the scope thereof other than by the terms of the appended claims.

What we claim is:

1. Air conditioning apparatus including an air chamber having axially aligned sections, a iilter in each of said sections, means in one of said sections and .between said fllters for inducing the circulation of air through said lters, and means for adjusting the longitudinal position of one of said sections relative to thek other oi' said .sections whereby said sections may be variably spaced.

2. Air conditioning apparatus including an air chamber having open ended axially aligned tubular sections one movable with respect to the other, a lter in each of said sections, means in one of said sections and between said nlters for circulating air through both of said illters when the sections are in end to end contact and for circulating air through only one of said sections when the sections are separated.

3. Air conditioning apparatus including two axially aligned open endedtubular sections, one movable relative to the other, the other adapted to be positioned for communication with the ex- CLARENCE wfmm EIMOND J. GERoNDAm.
